Yes, interesting. And importing MusicXML is also important and desirable.

Dear All, One interesting thing that could be implemented as a function could be a form of generating Negative Harmony. In the video below, there are some explanation of what it is and the origin in the Levy book. It was a trendy topic due to the Jacob Collier interview. And there are a lot of fun videos making versions of pop tunes using negative harmony. The way I understand it, it is simply a kind of mapping notes in relation to an axis, like in the figure below. So we need a function that could map a note in any register to another note in the closest register to the first on. So, any C note will be mapped to G, all Db to F#, all D to F, all, Eb to E, all B to Ab, all Bb to A. It´s also possible to generate other mappings as well. I think that replace map or substitute map can do the job, but I´m not sure (I will try), but I find interesting to post it here to explore the idea. All the best, Julio It´s kind of funny to sse in this por versions how every is upside down and how you can generate an entirely new song from exactly the same material. POP TUNES with negative harmony:

Great, Janusz ! Thank you ! Best, Julio

It would be great to have it automated because its painful to make it in notation software...

Hello, Friends I´d like to ask if there is some support in MusicXML for Stemlet notation (as in the example below) and if it can be accomplished in the OMN Lingo. I like this kind of writing for rhythmic stuff (the downbeat is more clear, IMHO). All the best, Julio

Heavy pressure by Monsieur Boussuge ! Indeed, really important and time saver for the composer. This would let us import stuff, maintaining the attributtes (dynamics, markings) of existing scores. All the best ! Julio

Looking forward to this. Now I´m trying to get some Ravel Piano scores onto OMN to make some tweaks.

Thanks, Stephane !

Dear All, I´m doing some melodic permutations and I have a question about replace-map: Here are four elements permutations, generated by: (permute '(1 2 3 4)) (setf permut4 '((1 2 3 4) (1 2 4 3) (1 3 2 4) (1 3 4 2) (1 4 2 3) (1 4 3 2) (2 1 3 4) (2 1 4 3) (2 3 1 4) (2 3 4 1) (2 4 1 3) (2 4 3 1) (3 1 2 4) (3 1 4 2) (3 2 1 4) (3 2 4 1) (3 4 1 2) (3 4 2 1) (4 1 2 3) (4 1 3 2) (4 2 1 3) (4 2 3 1) (4 3 1 2) (4 3 2 1))) Here are the pitch material to be permutated: (setf permutcontent '((1 cs4) (2 d4) (3 e4) (4 g4))) I used the REPLACE MAP FUNCTION, like this: (replace-map permutcontent permut4) THE RESULT: ((c4 d4 e4 g4) (c4 d4 g4 e4) (c4 e4 d4 g4) (c4 e4 g4 d4) (c4 g4 d4 e4) (c4 g4 e4 d4) (d4 c4 e4 g4) (d4 c4 g4 e4) (d4 e4 c4 g4) (d4 e4 g4 c4) (d4 g4 c4 e4) (d4 g4 e4 c4) (e4 c4 d4 g4) (e4 c4 g4 d4) (e4 d4 c4 g4) (e4 d4 g4 c4) (e4 g4 c4 d4) (e4 g4 d4 c4) (g4 c4 d4 e4) (g4 c4 e4 d4) (g4 d4 c4 e4) (g4 d4 e4 c4) (g4 e4 c4 d4) (g4 e4 d4 c4)) THE QUESTION: What if I want to replace one item (like a pitch) for a list of melodic pitches ? How to proceed ? For example: Instead of substitute a C4 for the number 1, I want to substitute a list of notes, like (cs4 ds4) (setf permutcontent '((1 cs4 ds4) (2 d4) (3 e4) (4 g4))) When I set this, a get only the cs4 permeated... Best, Julio I got it ! All the material must have the same number of elements, like (setf permutcontent '((1 (c4 cs4)) (2 (b4 ds4)) (3 (c5 f4)) (4 (cs5 ds4)))) Resulting in: ((c4 cs4) (b4 ds4) (c5 f4) (cs5 ds4)) ((c4 cs4) (b4 ds4) (cs5 ds4) (c5 f4)) ((c4 cs4) (c5 f4) (b4 ds4) (cs5 ds4)) ((c4 cs4) (c5 f4) (cs5 ds4) (b4 ds4)) ((c4 cs4) (cs5 ds4) (b4 ds4) (c5 f4)) ((c4 cs4) (cs5 ds4) (c5 f4) (b4 ds4)) ((b4 ds4) (c4 cs4) (c5 f4) (cs5 ds4)) ((b4 ds4) (c4 cs4) (cs5 ds4) (c5 f4)) ((b4 ds4) (c5 f4) (c4 cs4) (cs5 ds4)) ((b4 ds4) (c5 f4) (cs5 ds4) (c4 cs4)) ((b4 ds4) (cs5 ds4) (c4 cs4) (c5 f4)) ((b4 ds4) (cs5 ds4) (c5 f4) (c4 cs4)) ((c5 f4) (c4 cs4) (b4 ds4) (cs5 ds4)) ((c5 f4) (c4 cs4) (cs5 ds4) (b4 ds4)) ((c5 f4) (b4 ds4) (c4 cs4) (cs5 ds4)) ((c5 f4) (b4 ds4) (cs5 ds4) (c4 cs4)) ((c5 f4) (cs5 ds4) (c4 cs4) (b4 ds4)) ((c5 f4) (cs5 ds4) (b4 ds4) (c4 cs4)) ((cs5 ds4) (c4 cs4) (b4 ds4) (c5 f4)) ((cs5 ds4) (c4 cs4) (c5 f4) (b4 ds4)) ((cs5 ds4) (b4 ds4) (c4 cs4) (c5 f4)) ((cs5 ds4) (b4 ds4) (c5 f4) (c4 cs4)) ((cs5 ds4) (c5 f4) (c4 cs4) (b4 ds4)) ((cs5 ds4) (c5 f4) (b4 ds4) (c4 cs4))) But would be nice to MIX different number of elements...

I Love pieces with Scores !! Thank you and congrats for the music, Stephane ! Sounds great ! Best, Julio

Very Cool ! opmo code/score avaiable ? Best, Julio

Cool ! I'm curious !! Best, Julio

When it will be released ? Best, Julio

wow !!! Thanks !! Best, Julio

Thank you, Janusz ! I'm using this with the new closest-path function. Best, Julio

Dear Friends, When evaluating this (cmd+1) '(h (g3f4b4db5) (c4 maj7)) as snippet, I get this: Why is that c4 alone there in the beginning of snippet ? Best, Julio

Dear André, It's all solved with :start option ! You can decide a "model" voicing for the voice-leading ! Very cool ! Best, Julio Thank you, Janusz !

Dear Friends, Very basic question: I use some old VSL sample .gig files with gplayer. I really like this libraries and the way it sounds. The combination patches alternate sounds via keyswitches in the lower range of keyboard (or the upper range in some instruments). Something like: C normal sound C# pizz D marcato etc Can I use this keyswitches in the OMN lingo, without having to send the midi note itself to activate the keyswitch, something like: (marcato e c4 d4 s legato fs4 g4 cs5 eb5 ) Opusmodus will send the keyswitches as a hidden midi note in the expression ? All the best, Julio

Dear Janusz, When I evaluate this expression: (closest-path '(b3eb5g3 cs6e7gs3 b4f5g6 f7e5c2 d4f7e4 gs7e2a8)) I get this: I was expecting this: Maybe a good idea would be something like a octave compress option. Best, Julio

Done !!! All the best, Janusz ! Julio

Yes, it also occurred to me to change the name. If this is really an sucessful algorythm for the closest-path, I would suggest to change the old function to another name. Thank you, Janusz ! Best, Julio

Dear Janusz, In my version of Opusmodus, I get this: But maybe it's important to have all compressed within one octave, like this: (g3b3eb4 gs3cs4e4 b3g3f4 c4f3e4 d4e4f3 e4gs3a3) What do you think? Best, Julio

I think voice-leading is one of the hardest things !!

Dear Friends, Avner, I noticed exactly the same behaviour. I feel a contradiction in having two results for something called "the closest path", because "the closest path", in my interpretation, means only one solution: the one in which the sum of the semitones of all voice-leading moves are the less. It's logically impossible to have "the closest path" with two solutions. You cannot have the cake and eat it too... If the function alternate between two solutions, maybe could be the case that two solutions would sum the same amount of semitonal moves, but the example above do not seems to be that case. After I realized it, I tried to find a way to assure a more accurate expression to represent that one "closest" solution. Janusz, what do you think ? All the best !! I love Opusmodus !! Thank you ! Best, Julio

Thanks a lot !! Best !
